Answer:
 { x | -3 <= x < +1 }
Step-by-step explanation:
We note that the graph occupies from x=-3 to x=+1, while -3 is a value included (endpoint is solid), and +1 is excluded (endpoint hollow).
Thus the domain is { x | -3 <= x < +1 }
 
        
             
        
        
        
Answer:
0.1606 = 16.06% probability that the number of births in any given minute is exactly five.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
 is the mean in the given interval.
 is the mean in the given interval.
In this question:
We only have the mean during an interval, and this is why we use the Poisson distribution.
The mean number of births per minute in a given country in a recent year was about 6.
This means that 
Find the probability that the number of births in any given minute is exactly five.
This is P(X = 5). So

0.1606 = 16.06% probability that the number of births in any given minute is exactly five.

Answer:
y + 5 > -2 i.e. option 4.
Step-by-step explanation:
An inequality is shown in the number line by an arrow and we have to identify the inequality from the options given.
It is clear from the given figure that the y variable is plotted and its value is greater than - 7 but not including - 7.
Therefore, option 4 which gives the inequality y + 5 > -2 will be the correct answer.
As it gives y > - 2 - 5 i.e. y > - 7 (Answer)
